Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 90 ppm/° C. measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 91.8 ppm/° C. and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

A hot melt adhesive film, and a preparation method, use, and an organosilicon polymer thereof are provided. The hot melt adhesive film includes: an inner layer, which is a polyolefin elastomer (POE); outer layers, which are an ethylene-vinyl acetate (EVA) copolymer on two surfaces of the inner layer; and intermediate layers, which are an organosilicon polymer between the inner layer and the outer layers. As intermediate layers, the organosilicon polymer plays the role of connection and transition, improves a bonding force between EVA and POE layers, and improves the stability of the hot melt adhesive film during long-term use. The hot melt adhesive film can be used as a packaging material for solar panels, touch screens, and the like.

An impact-resistant film comprises at least one layer of an elastomeric polymer material and an adhesive layer.

Provided is a pressure sensitive adhesive sheet for tires that enables continuous and efficient labeling on tires using a labeling apparatus. The pressure sensitive adhesive sheet includes a release material (C), a first pressure sensitive adhesive layer (B1), a first substrate (A1), a second pressure sensitive adhesive layer (B2), and a second substrate (A2), in this order, and satisfies Requirement (1): in a planar view of the pressure sensitive adhesive sheet, the outline of the first pressure sensitive adhesive layer (B1) exists inside the outline of the second substrate (A2); and Requirement (2): the MD stiffness of the second substrate (A2), measured in the Gurley method according to JIS L 1085, is 0.10 mN or more.

A screen protector (5) for a mobile electronic device with a touch screen. The screen protector comprises a flat laminated film comprising a layer (2) of polyethylene terephthalate (PET) bonded to one face of a layer (3) of thermoplastic urethane (TPU) and a layer (4) of adhesive on the opposite side of the TPU layer. The PET layer is less than 50 μm thick and wherein the adhesive layer provides a tack force of greater than 5 g/cm.sup.2. The relatively thin layer of PET with the relatively high tack force adhesive provides a screen protector particularly suited to a device with a curved screen.

The present disclosure belongs to the technical field of disposable toilet seat covers, and in particular to a novel portable toilet seat cover. The novel portable toilet seat cover comprises more than one unit layers, each unit layer comprises a surface layer, and a base layer. The surface layer is arranged at a first surface of the base layer, and the bottom layer is arranged at a second surface of the base layer; the surface layer is a release layer for preventing skin adhesion.

A thermosensitive adhesive label comprising a laminate film of a first film layer and a second film layer, and a thermosensitive adhesive layer on the surface of the second film layer side of the laminate, wherein the Bekk smoothness of the surface of the first film layer side of the laminate film is from 2000 to 20000 seconds, the Bekk smoothness of the surface of the second film layer side of the laminate film is from 800 to 20000 seconds, the contact angle with water of the surface of the second film layer side of the laminate film is from 20 to 80°, and the surface strength of the thermosensitive adhesive layer is from 0.6 to 1.8 kg-cm.

A multi-layer surface covering includes at least a first and a second layer made of a polyvinyl chloride material, each of the two layers having a different density. One of the two layers includes a pigment such that the layer resembles teak. A surface of the colored layer is at least partly abraded to resemble a wood grain. The surface covering may additionally include grooves cut into the surface to resemble individual wood planks. The grooves additionally provide traction and drainage of liquid from the surface to an edge of the covering.

A system for protecting a surface of a substrate includes a protective film, which is configured to be applied and secured to the surface, as well as a backing on an adherent surface of the protective film and an application tape over an exterior surface of the protective film. Protruding features, such as tabs, adjacent to different peripheral edges of the protective film may enable removal of the backing and the application tape from the protective film, and may include features that indicate the order in which each protruding feature is to be grasped to peel its corresponding element away from the protective film.
